That's not a torque curve, it's a torque shelf. O_O

It's incredible that the GTX technology allows the turbo to reach those level ( E85 or not) with only 10 PSI. It's no wonder people are into 600s with the 3076

I'm drooling over that, that's the closest I've ever seen to a perfect WOT dyno graph that isn't artificially torque limited by the tuner. Flat line of torque, HP goes up and to the right, it's a work of art.

Yeah, but what kind of damage is that non limited torque curve doing to the engine? (honestly curious)

Torque stress is lower on the rotating assembly as RPM increases. Lower RPM torque is what breaks things. I think the reason the torque line is so smooth is because boost is being tapered in gradually (this is how I had my car tuned). It's great because it helps with predictability, stabilization, and not being bored with the car after 5k RPM. When you have torque ramp in early by shoving boost in and then having to hold it there, it doesn't feel as rewarding to rev the car out

I guess I will add mine even though I am going to puling it off the car PM if your interested

Why are you removing it? The Sprintex car I've been in felt perfect, it's exactly what I'd want if I were an OEM+ kind of guy

Keep it short and sweet:

1)CARB aka California and smog
2) I want to compete in the SoCal FT86 cup and with all my mods it would put me in the modified group which I have zero shot as a driver to compete in. Plus this Kit is the worst on the track as it does heat soak quickly in high temps. I want to get better as a driver and this will allow me compete in the street class which I have a much better shot at

Been running this tune from DBW Motorsports in Atlanta for about a year now and going strong!!! Ready to update my fuel system and see what she can do with racefuel/e85.

made 293 whp 8psi and 234 5psi on what is probably 93 RON in the US. 5 psi is just for putting around town.

Quite literally the reason I will go with a Jackson racing C30 supercharger
